A jack lift device for lifting and positioning loads includes a tube, a pipe and a hoist. The tube is configured to insert into a hole in a top of a step ladder. The tube is configured to couple to the step ladder so that the tube is positioned substantially vertically. The pipe is complementary to and selectively slidably positionable within the tube. A plate is coupled to and extends perpendicularly from an upper end of the pipe. A hoist is coupled to the tube and operationally coupled to the pipe. The plate is configured to position a load, such as a metal conduit. The hoist is positioned to selectively compel the pipe vertically through the tube so that the load that is positioned on the plate is positioned at a desired height, such as proximate to a joist to which the metal conduit is to be is coupled.
